Bacon isn’t typically in regular rotation for dieters or those concerned about heart health, unless it’s of the limp, lower-fat turkey variety. But a new invention might change all that: skinny pigs.

NPR reports that scientists in China have used genetic engineering to make 12 pigs with 24-percent less body fat than their huskier counterparts. Published in the Proceedings of the National Academy of Sciences, the effort wasn’t started because of health-conscious consumers in mind but rather by pig farmers hoping to save money. As the news outlet explains, keeping pigs warm in the winter is expensive, and the animals have a hard time regulating their internal temperatures. Thus, the interest in skinny pigs.

The team knew that a protein found in fat, known as UCP1, helps regulate body temperature and burn fat. Pigs don’t have this protein, so the team used the gene-editing process known as CRISPR-Cas9 to add what nature had not. The process makes it possible to alter DNA in an organism, and there’s been talk about using it to treat diseases, make “designer babies,” or in this case, skinny pigs. According to the researchers, these lighter breeds could have a huge impact on the industry.

“UCP1 KI pigs are a potentially valuable resource for agricultural production through their combination of cold adaptation, which improves pig welfare and reduces economic losses, with reduced fat deposition and increased lean meat production,” the authors write in their study.

The new pigs are a testament to the capabilities of gene editing. “This is a paper that is technologically quite important,” R. Michael Roberts, animal sciences professor at the University of Missouri, told NPR. He’s not linked to the research but edited the paper. “It demonstrates a way that you can improve the welfare of animals at the same [time] as also improving the product from those animals—the meat.”

But don’t expect to bring home the diet-friendly bacon anytime soon. Genetically modified (GM) foods continue to be a contentious subject. Proponents believe that it could help feed millions of hungry people amid climate change and population growth. Others balk at the idea of eating science experiments.
